Moderate to heavy accumulations are likely for much of the northern & central Rockies as well as north-central parts of the United States. It is too early to determine specific snow amounts but travel issues can be expected from Colorado north into Wyoming and Montana as well as into the Dakotas. Strong winds will help reduce visibility along with heavy snow for the Dakotas and Minnesota.
